In Biology, Polarization Is A Good Thing
Using a molecular cellular compass, individual cells in complex organisms know which way is up or down, in epithelial cells known as apical-basal polarity. Determining the orientation is essential for an individual cell to perform it's designated tasks. Now it appears that the same compass also defines the direction of cells when migrating by establishing a morphological back and a front.

Chemicals Found In Cherries May Help Fight Diabetes
Perhaps George Washington wouldn't have chopped down his father's cherry tree if he knew what chemists now know. They have identified a group of naturally occurring chemicals abundant in cherries that could help lower blood sugar levels in people with diabetes. In early laboratory studies using animal pancreatic cells, the chemicals, called anthocyanins, increased insulin production by 50 percent. Army Sexual Assault Prevention and Response Program

A biological sensor that catches infections on hospital catheters at an early stage has been developed by young scientists. The device aims to prevent painful urinary infections in elderly hospital patients. It consists of a genetically engineered device suspended in liquid that could be painted onto the end of a catheter outside the patient's body. This liquid contains a protein which seeks out and latches onto a small molecule called AHL, which is secreted by bacteria and found in these kinds of infections. The 10,000-Step Guide to Fitness
This feature describes the concept of walking 10,000 steps per day (using a pedometer to keep track) to obtain health benefits. "The British Heart Foundation (BHF) says 10,000 steps a day (about five miles) can give you a healthy heart and reduce body fat."It includes quick tips regarding the 10,000-step challenge, statistics on fitness in Britain, and an illustrated description of how a pedometer works.
